You have completed adjusting the current modes of the NI 4070/4072.
Select one of the following options:
♦ If you are calibrating an NI 4070, refer to one of the following sections:
• Verification Procedures—to verify your new calibration coefficients
before saving them to the EEPROM
• Completing the Adjustment Procedures—if you do not want to verify
the adjustments you have just made
♦ If you are calibrating an NI 4072, refer to the Adjusting Capacitance and
Inductance (NI 4072 Only) section.

♦ If you are calibrating an NI 4070, skip this section and select one of the
following options:
• If you want to verify the new calibration coefficients before saving
them to the EEPROM, repeat the Verification Procedures section
(except for the Initial Setup section).
• If you do not want to verify the new calibration coefficients, go to the
Completing the Adjustment Procedures section.
